/**
 * Transcript source adapters — each AI coding tool persists chat transcripts
 * somewhere different; this module knows where, and how to pull out the
 * genuine human-typed messages. The harvest orchestrator (harvest.ts) treats
 * every source identically: discover sessions → extract user messages →
 * redact → LLM claim extraction → proposal queue.
 *
 * Supported:
 *  - claude-code      ~/.claude/projects/<path-slug>/*.jsonl
 *  - codex            ~/.codex/sessions/(**)/*.jsonl (rollout files, matched by cwd)
 *  - copilot-vscode   VS Code workspaceStorage/<hash>/chatSessions/*.json
 *  - cursor           Cursor workspaceStorage/<hash>/state.vscdb (SQLite)
 *
 * Not supported: Devin (cloud-hosted, no local transcripts).
